Cleaning compound.



UNITED STATES PATENT OFFICE.

JOHN CALLAHAN, OF SEATTLE, WASHINGTON CLEANING COMPOUND.

Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed May 3, 1905. Serial No. 258,723.

vented certain new and useful Improvementsin Cleaning Compounds, of which the following is a specification.

The present invention relates to improvements in boiler-cleaning compounds, and has for its primary object the provision of a compound which embraces but few ingredients, which are comparatively inexpensive from a mercantile standpoint, and when combined as pointed out in the following will be very eflicient.

As is well known, steam-boilers become incrusted and corroded, and the scale being a non-conductor of heat, a decrease in efficiency of the boiler results. My improved compound removes this scale and immediately stops corrosion or galvanic action and will neutralize and destroy all effect of oil or grease, which is encountered particularly in marine condensing work.

The formula of my compound is as follows:

silicate of soda, seventy-nine per cent. cutch,

ten per cent. glucose, ten per cent. carmin, one per cent. In this compound the cutch,

which is a powerful astringent, is employed, preferably, in the extract form. These ingredients are thoroughly mixed and boiled, and, if necessary, water or any other suitable liquid can be added during the boiling process to give a proper consistency to the compound and prevent burning thereof, as is obvious.

The compound in operation is applied to the interior of the boiler in the form of a thin coating, and aside from accomplishing the results referred to in the foregoing it has been demonstrated by actual practice to stop ordinary leaks around rivets and the like.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States of America, 1s

1. A cleaning compound having incorporated therein silicate of soda, cutch and glucose.

2. A cleaning compound having incorporated therein a silicate, and an astringent extract and glucose.

3. A cleaning compound having incorporated therein an alkaline silicate, and an astringent.

4. A cleaning compound having incorporated therein a silicate and an astringent extract.

5. A cleaning compound composed of seventy-nine per cent. alkali, ten per cent. cutch, ten per cent. glucose, and one per cent. carmin.

Signed at Seattle, Washington, this 26th day of April, 1905.

JOHN CALLAHAN.
